忍者子弹敌人

入口：AppDelegate->applicationDidFinishLaunching()

->CCScene *pScene = HelloWorld::scene()

------------>

HelloWorld::scene()->create();

->create()

-->调用CREATE_FUNC(HelloWorld)->调用HelloWorld->init()方法

背景色设置

CCLayerColor::initWithColor(ccc4(0,255,0,100));

创建精灵：

CCSize winSize = CCDirector::sharedDirector()->getWinSize();

CCSprite *player = CCSprite::spriteWithFile("Player.png",CCRectMake(0, 0, 27, 40));

//设置位置

player->setPosition(ccp(player->getContentSize().width/2,winSize.height/2));

this->addChild(player);

//设置可触摸

this->setTouchenabled(true);

//设置背景音乐

SimpleAudioEngine::shareEngine()->playBackgroundMusic"background-music-aac.wav"

,true);

 

 

this->setTouchenabled(true);--->重载方法

void ccTouchesEnded(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent)

CCCallFuncN *callFunc = CCCallFuncN::actionWithTarget(this,callfuncN_selector(HelloWorld::spriteMoveFinished));//移动结束后回调spriteMoveFinished方法

CCSequence *seque = CCSequence::actionOneTwo(moveto,callFunc);//执行的顺序

添加动作结束特效

SimpleAudioEngine::sharedEngine()->playEffect("pew-pew-lei.wav");

 

动作调用的顺序是：

在init()中

addTarget()

update()--->碰撞检测

之后-->触摸->产生子弹

在子弹和敌人结束动作后调用

spriteMoveFinished()//显示失败

 

  增加结果显示层

GameOverScene

CC_SYNTHESIZE_READONLY(cocos2d::CCLabelTTF*,_label,Label);

//显示层变量：CCLabelTTF*,_label, 只有getLabel方法

调用->retain()方法一定要调用release()方法

CCDelayTime* delayTime = CCDelayTime::actionWithDuration(3);
CCCallFunc * callFunc = CCCallFunc::actionWithTarget(this,
callfunc_selector(GameOverLayer::gameOverDone));
CCSequence *sequence = CCSequence::actionOneTwo(delayTime,callFunc);
this->runAction(sequence);

在延时一定时间后 回调gameOverDone 方法

gameOverDone -->

CCDirector::sharedDirector()->replaceScene(HelloWorld::scene());

切换回HelloWorld场景
